摘要
本文论述了光纤光栅辐射特性.通过耦合模理论首次给出了单模光纤偏振态(SOP)与光纤光栅远场辐射损失之间的关系.实验数据与理论分析基本吻合.利用光纤光栅这一关系可实现光纤偏振态在线检测.
The radiation properties of fiber gratings are described in this paper. The relationshipbetween the fiber state of polarization(SOP)and the radiation loss of fiber grating is given for the firsttime in this paper. The experiment data are accordant with theory analysis. By this relationship, thefiber SOP can be measured in line.
